SPECIFICATION forming part of Letters Patent No. 664,820, dated Decanter 2'5, 1906;

Application filed December l, 1899. Serial No. 738,774. (No model.)

ft'b all whom t may; coreografi.-

Beit known that LJULIUS A. PERKINs,a citi- Zen of the United Stat-es, residing at Omaha, county of Douglas, and State of Nebraska, have invented an Improvement in Rollerl-earings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

Theinvention to be herein described relates to roller-bearings of that type in which a series of bearing-rollers have a planetary movement between a box or hub and a journal or shaft, the rollers being preferably sustained and separated one from the other in a cage.

I have herein represented my invention as applied in a bearing for a railway-car wherein the journal rotates and the box is stationary; but my invention is equally Well applicable to a roller-bearing in which the journal is stationary and the box rotates.

In my invention the rotating part of the roller-bearing with which the bearing-rollers coperate has connected traveling-cage controllers or end guards, with which may contact at intervals under certain conditions the ends of the cage, said cage running for a greater portion of the time out of contact with the traveling-cage controllers, said controllers being on the journal when it rotates and on the box when it rotates.

In the form in which I have herein chosen to illustrate my invention, it being one of the best forms now known to me, the cage is composed ofsuitable end walls or rings united iirmly and rigidly by cross-bars, the latter separating the cage into roller receiving spaces, in which are suitably alined a series of bearingrollers having a planetary motion between the box and journal and contacting at diametrically opposite points with the inner surface of the box and with the outersurface of the journal. These rollers are alined in the cage by non-rotatable axial supports, extending inwardly from the inner sides of the end walls of the cage and entering the ends of the bearing-rollers, said supports in one preferable form being represented as spindles extended through axial holes in the bearing-rollers, the holes in the rollers being sufficiently larger than the diameter of the axial supports as not to contact therewith in the operation of the bearing. The axial supports are xed or made non-rotatable in or with relation to the end walls of the cage, and there is interposed between these nonrotatable axial supports and preferably the inner Walls or chambers made in the ends of said bearing rollers suitable antifriction means, which may be balls, which surround said axial supports and sustain the weight ot' the cage from the ends of the rollers, said antifriction means also by interposition between the ends of the bearing-rollers and the inner walls of the cage preventing any contact Whatever between the ends of the rollers andthe cage. The axial supports or alining means forthe bearing-rollers (in practice I for the best results composed of steel) are fixed in the cage, so that they cannot under any conditions of the bearing in use rotate them, and consequently the balls have a rigid and un Varying support in the planetary motion of the bearing-rollers.

The cage in the direction of the length of the bearing-rollers is suciently'shorter than the distance between the traveling-cage controlling surfaces or end guards, or their acting faces of whatever material, to enable the cage when the bearing is in use and occupying a position between the box and the jonrnal and also between said cage-controllers or end guards or their faces, of any materialJ to run freely between said faces without contacting therewith or with either the journal or the box, and consequently I designate said cage as a iioating cage, it moving in the same direction with the traveling-cage controllers, but at a slower speed, said cage running normally freely in the open space between the faces of said traveling-cage controllers as a boat runs in a raceway, t-he cage sliding in the wider space between the faces of the traveling-cage controllers due, it may be, t-o the influence of gravity-as, for instance, should the surfaces of the journal or box when in action get out of true horizontal planes or should the surfaces of the rollers get out of parallelism one with relation to the other-and then in either case one or the other of the ends of said cage is liable to move toward and be struck by the faster-traveling cage-controller, the blow of said traveling surface against the end of the cage being suffi- IOO cient to move the cage laterally in an opposite direction and return it again int-o its proper free -running positionbetween the faces of the traveling-cage controllers.

When the traveling-cage controllers cornposed of metal strike against the metallicl end walls of the cage, the blow of the cage-controller against the cage is quick, so that the metal faces do not cling together for a sufficient length of time to produce any perceptible wear either in the cage-controller or the end walls of the cage, yet to reduce the wearing of the roller-bearing to the minimum I have herein shown and shall in practice preferably interposc between the travelingcage controllers and the ends of the cage nonmetallic washers, preferably of vnlcanite or equivalent material, applied so as to constitute acting faces for said cage-controllers,and should there be any wear in said washers they may be readily renewed, restoring the bearing` to its original state of efficiency.

As one good form of fixing the axial supports about which the bearing-rollers revolve when said supports are represented as spindles I may provide the ends of the spindles with faces or portions other than round and may spin or inturn the metal of the cage surrounding the ends of the spindles located in alined holes in the cage, the ends of the spin- -dles not extending to the outer faces of the cage, the material s0 spun or inturned and entering said holes forming an abutment which by contact with the ends of the spindles retains the spindles from rotation in the cage and also restrains all longitudinal motion of the spindles in the cage, and spindles so held and locked may be easily punched or driven out and replaced whenever desired. This invention is not, however, herein limited to the precise construction of the supports or centering means represented in Figure l, and instead I may employ any other usual or suitable non-rotatable centering or alining means shaped to sustain a series of balls acted upon externally by a part of the bearing-roller at its end, and so, also, this invention is not limited in all instances to the exact construction of the antifriction means interposed between the rollers and the inner sides of the cage and surrounding the centering means, and instead I may employ any other usual or suitable antifriction means.

The bearing-rollers alined in the cage sustain the weightof the load, and in action said rollers simply roll or have a planetary motion between the inner surface of the box and the outersurface of the journal, and this movement is without the production of friction, andv by the interposition of the antifriction means between the rollers and the cage and the centering devices and the rollers the ends of the rollers may in their rotation run without rubbing friction against the cage or against the centering means.

The bearing-rollers in one preferred form of my invention herein represented have chamwith both the inner surface ofthe box and theY outer surface of the journal, and as aresult of this contact it has been found that the continued hammering of the iianges in the line of their contact with the balls and between the balls and the inner surface of the box and the outer surface of the journal results not only in crystallizi ng the flanges at the ends of the rollers, but also owing to the endwise motion of the rollers between said box and journal the ends of the rollers in the long use of the roller-bearing wear a sort of groove both in the box and .the journal, and hence to obviate this crystallization of the flanges of the rollers and also the wearing of the grooves in the surfaces referred to I have provided for a free space between the rollers at their ends and the innersurface of the box and the outer surface of the journal opposite the-flanged ends of the rollers, so that under no conditions can said flanged ends meet or contactwith either the surface of the box or of the journal, and preferably I provide this space by reducing the diameter of the rollers at their ends at and about the flanges. In this way by relieving the anges so that they do not contact at their exteriors with anything it is possible to run the rollers for any desired length of time and yet maintain the flanges in original working condition.

A roller-bearing of the class herein specied does not need oil to enable it to run freely, yet in practice to prevent rust of the Voperative parts of the bearing it is necessary to grease the surfaces over or with relation to which the bearing-rollers travel, and it is also understood that dust. cannot be entirely excluded from the box, and dust uniting with the grease forms a residu nm,which,if allowed to accumulate upon the surfaces of the bearing-rollers, tends to throw them out of parallelism with relation to the inner surface of the box and the outersurface of the journal, so that for the best results this residuum must be taken care of and the bearing-rollers must have their surfaces kept clean and unobstructed. Should this residuum be allowed to accumulate, the rotation of the bearingrollers might be entirely obstructed, which would render the hearing in a short time inoperative. rlo care for this residuum as produced, a receptacle or pocket has been provided, and said receptacle in practice willbe so located with relation to the box and journal that the residuum under the action of gravity may drop from the rollers and enter the receptacle, and preferabljT if the journal rotates it will be made in the box, and if the box rotates it will be made in the journal,

IOO

and the receptacle will preferably be made in said box or in said journal at a point Where the pressure of the load being carried is least.

The rollers are freed from any accumulations thereon, as stated, by gravity, and to enable gravity to so act the peripheries of the rollers in each complete cycle of their movement must be exposed over the receptacle, and consequentlyY the receptacle for the best results should be ot a length in the direction of the longitudinal axis of the journal some what in excess of the length of said bearingrol'lers; but the receptacle, instead of being one large open space, is broken up by bearing surfaces or faces to present an irregular space or spaces, said spaces being between the faces, said faces occupying a position in substantially the circle of the inner bearingsurface of the box or the exterior bearing-surface of the journal, whichever has the receptacle made in it, that said bearing-rollers in their planetary motion may never be wholly without support, for should they enter a large receptacle the said rollers running at a high speed would, due to centrifugal action, un duly wear not only the centering means, but the balls and the flanges at the ends of the rollers, and as the rollers emerge from the receptacle they would strike against a shoulder at the farther side of the receptacle, which in the rapid running of a bearing would exert a blow that would be excessively injurious to the bearing-roller and would strain and Wear not only the danges of the rollers, but the balls and the centering means and the cage construction, and consequently the need of the receptacle presenting surfaces or faces to always contact with some portion of each roller as it passes the receptacle.

The surfaces at and about the receptacle which constantly sustain the rollers when crossing the receptacle are so located each with relation to the other that each bearingroller in crossing the receptacle will have one or another portion thereof exposed that any particles collected upon or carried by the roller at its unexposed part may by gravity enter the receptacle, the object being that substantially all parts of each roller be exposed to au open part of the receptacle during the time occupied by each roller in crossing the receptacle. In order that the residuum droppinginto the box may be so collected and that it may be readily washed out or removed, l preferably form the lower side of the box as an incline and l provide the box at its bottom and top with suitable plugs which when removed will enable a liquid to be run through the box t-o cleanse it and the bearing-rollers and the journal.

l have provided suitable end thrust means to reduce the friction resulting from the contact of the end of the journal with the end of the box, and in the form in which my invention is herein embodied, the journal ro tating, l have made one of the traveling-cage controllers detachable from the journal, and

I have interposed between said journal and said detachable-cage controllers a suitable washer, preferably of non-metallic material.

In the accompanying drawings, illustrating one practical form of this invention, Fig. l shows in vertical section a roller-bearing supposed to be adapted for use in railway-car construction, the box being stationary and the journal rotating, the end of the journal being broken out to represent the construction of the detachable or travelingcage controller represented as applied to the rotating journal. Fig. 2 shows a modiied form of the lower part of the box and its receptacle, the section being a longitudinal section. 3 is a section in a horizontal plane taken through the box to show its under side and the receptacle therein with its surfaces to maintain contact with the bearing-rollers. Fig. 4 is a section of the bearing shown in Fig. l on the dotted line x2. Fig. 5 is an end view of the cage removed from the journal and box. Fig. 6 shows a modification of my invention as regards the receptacle for dirt and refuse. Fig. 7 is a section of Fig. 6 in the dotted line mi; and Fig. S represents part of the journal,showl ing a dierent Way of detachably applying the traveling-cage controller to the journal supposed to be rotative, as in Fig. l.

A represents a journal supposed to be rotative, it having a surface JA', said journal being represented as the journal of a railwaycar; but it may be any journal or any part of a rotative shaft.

The box or stationary member C surrounds the journal A, and the journal receives about it a series of suitable bearing-rollers B of any desired number, I having herein chosen to representseven such rollers. (See Figs. and 5.) These bearing-rollers are represented bored throughout from end to end, as at B', and the ends of the rollers are provided with countersin ks or chambers, leaving at the ends of the rollers lianges B2, which do not contact with either the box or journal, a space being left outside the tianges by reducing the anges in diameter.

The bearing-rollers B are shown as alined and so maintained in spaces of a suitable cage composed of rings D, united firmly by suitable arms or cross-bars D', fixed or held rigidly at their ends to said rings to thus make ofthe rings and arms or bars a rigid cage, the bars separating the cage into roller-receiving spaces. The opposite ends of the cage are provided with bores through and through which aline one with the other, and asl have n chosen to illustrate my invention in Fig. l the bores receive centering or alining means, represented as spindles D2, which are provided, as represented, at their opposite ends with surfaces l0, (shown at the left in Fig. 1,) and the ends of the spindles terminate in the bores of the cage and at a point within the outer side walls of the cage, and the spindles are retained against longitudinal motion in the cage, and they are also fixed so that they IOO IIO

cannot rotate in the cage by means of suitable abutments, as l2, made by upsetting portions of the cage to meet the ends of the spindles.

It is essential for the best operation of a roller bearing that the centering means should not rotate and that said centering means be rigidly and immovably fixed in the cages.

The spindles l)2 are of enough smaller diameter than the bores B in the rollers B that said rollers in their rotation cannot contact With the centering means.

The chambers in the ends of the rollers are of a diameter greater than the bores through the rollers, and said chambers within the flanges receive antifriction devices, preferably balls E, said balls contacting with the inner walls of the iianges and with the inner sides of the Cage and running in the rotation of the rollers and in contact with said centering means.

The antifriction means acts to prevent contact of the ends of the rollers with either the centering means or the cage.

In the use of bearing-rollers having flanges at their ends which are sustained at theirinner sides by balls, said flanges contacting with the inner surface of the box and the exterior surface of the journal, it has been found that the balls E in rptating about the supports hammer the flanges running at their exterior in contact with the inner surface of the box or the outersurface of the journal, and such hammering results in crystallizing the fianges, so that they readily disintegrate or break down, thus destroying the usefulness of the bearing.

By providing the spaces E2 between the exterior of the flanges of the rollers and the interior of the box and the exterior of the journal I have overcome the difficulty of crystallization of the flanged parts of the rollers, and these spaces as herein embodied are made by reducing the external diameter of the flanged parts of the rollers.

The bars or arms D', employed to connect the end Walls of the cage, are represented as provided with tenons d', which enter suitable holes made in the cage ends and are there fixed by upsetting, swaging, or in any other convenient manner.

ln Figs. l to 4 the lower part of the box is provided with a receptacle F for refuse or residuu m composed of grease and dust, as specifled, which may collect in the box in the operation of the roller-bearing, and the bottom of this receptable is preferably tapered somewhat, as at F', said taper leading to a suitable outlet closed by a plug F2, so that when said plug is removed kerosene or any other liquid inserted in an opening at the top of the box, which may be exposed by removing a plug F3, may liow through the box and wash from the surface of the bearing-rollers and the journal any refuse which may be accumulated thereupon.

In practice it has been found that dust com; mingling with the grease or oil used to prevent the bearing from rusting when not in operation Will, if not cared for, so accumulateY upon the surfaces of the bearing-rollers as to throw them out of parallelism with rela'- tion to the surface of the journal with which they contact or will so clog the said rollers that they will not rotate, and in either instance this accumulation of refuse is injurious to the bearing; but by providing the refis..V

use-receptacle and so locating it with rela- Y' tion to the box or the journal that any refuse particles accumulating upon the rollers may,

due to gravity, drop from said rollers and en- Y rollers are at all times sustained uniformly in their planetary movements. By providing a series of these supports extending more or Y less across the receptacle, an irregular-shaped receptacle is formed and the supports sustain Y at all times some part of each bearing-roller in its planetary motion about the journal,and said surfaces are so located one with relation to the other that substantially the entire surface of each bearing-roller is exposed at some time during its planetary motion opposite a space of the receptacle that any particles accumulated thereon may obey gravity and drop therefrom into the receptacle.

The supports G G G2 in Figs. l and 3 are represented ascrossing the axis of rotation of the journal at right angles; but said surfaces maybe arranged in any line, so long as they act to continually sustain the rollers and IOS IIO

leave spaces between them in which the refuse matter may drop by gravity.

The receptacle F is represented as 'of a Y length greater than the length of the bearingrollers, and were it not for the supports it II'S will be obvious that the bearing-rollers in the rapid movement of the cage containing 'the' said edge with a hard blow, which would not only wear but greatly strain the rollers, theV balls, and the centering means. So for the greatest efficiency of the bearings one or the other of the plurality of the supports at the sides of the spaces constituting the receptacle F must always act against and keep the peripheries of the bearing-rollers in their proper Y running line.

As the journal A rotates its shoulder H constitutes a traveling-cage controller, and

said jou rnalhas a second traveling-cage controller,(represented by a detachable end piece II,) said end piet-e being detachable from the journal in order that the cage and its bearing-rollers may be readily applied to the journal and put in position between the journal V and the interior of the box C.

The detachable traveling-cage controller I-I' is applied to the -iournal by means of a tenon, the tenon in Fig. 1 heilig on the cageeontroller and entering a socket in the journal; but this traveling-cage controller might have a hole through it, as represented in Fig. S, and a tenon, as H2X, might project from the journal A and enter the hole of said cagecontroller.

The face of the traveling-cage controller H and of the cage-controller H' are each provided with a non-metallic washer, as 101 and 102, said washers being preferably of vulcanite or its well-known substitutes, and the distance between the exposed faces of the noninetallic washers is greater than the length of said cage, sothat said cage in running may occupy a position, as represented in Fig. l, with its ends out of contact with either antifriction-washer, and said cage may in operation run freely in the space between the faces of the non-metallic washers without contacting therewith, the faces of said washers constituting the side walls of a raceway in which the cage may move freely without contact therewith except when for any reason the cage is caused to move lengthwise of the journal, in which event the cage, rotating in the direction of movement of the travelingcage controllers, but at a slower speed, will slide endwise between the faces of the nonmetallic washers and will meet one or the other of said washers, and they, traveling at a faster speed, will strike the end of the cage with a blow sufficient to quickly restore said cage into its free-running position.

It will be obvious that this invention would 1 not be departed from should I omit the noninetallic washers and should the ends of the cage meet the traveling-cage controllers composed of metal, yet the employment of the non-metallic washers is of the greatest benefit, because by their use the cage and the traveling-cage controllers are rendered practically indestructible and any wear which may be apparent in the roller-bearing by long-continued use may be readily compensated for by supplying new non-metallic washers.

In applying the detachable traveling-cage controller to the rotating journal I also prefer to interpose between the said cage-controller and the end of the journal antifriction means which in Fig. 1 is the non1netal lic washer or buffer 102; but in the modification Fig. S the non-metallic washer of Fig. 1 is divided in two parts 103 and 104.

The detachable traveling-cage controller II performs in the present embodiment of this invention an additional function-that is, the outer face of said surface impinges against suitable antifriction means in overcoming friction due to end thrust, and said antifriction means for good results may be balls M, arranged in an annular groove C4, made at the inner face of the head G3 of the box, said anifriction means occupying a position, as represented, without the axial center of the journal, said balls being retained in said annular groove by means of a keeper, represented as a plate D having a plurality of connected studs N, which are extended th rough holes in the fare of the box and there rigidly xed in position, preferably, by upsetting the ends of .said studs, the exterior of said plate M somewhat overlapping one wall of the groove C4 and contacting with the balls to keep them in said groove.

The outer face of the detachable controller H contacts with the balls O4 only when the journal slides longitudinally in the box or the box slides on the journal, and to cover this feature broadlyI shall use in the claims the term slide relatively in a line longitudinal of the axis of the journal,7 I thereby intending to cover the sliding of either with relation to the other.

The opposite or inner end of the box C may and will in practice have preferably some suitable form of dust-guard or packing, as

C2, not herein claimed as novel.

The box O may be of any usual shape and material, and its different parts may be suitably united by bolts, as O.

I believe that I am the first to provide a roller-bearing containing a plurality of bearing-rollers rotatable in a rigid traveling cage and alined in said cage by centering means non-rotatable in said cage with traveling-cage controllers the faces of which are separated from each other for a distance greater than the length of the cage, and I also believe that I ain the first to provide either a stationary box or a stationary journal with which cooperates a series of bearing-rollers with a receptacle to receive refuse which may form in theV bearing during its operation, and consequently I desire to claim this receptacle broadly and in whatever shape it may be made, said receptacle being in all instances so located either in the box or in the journal that refuse dropping from the peripheries of the rollers at their faces exposed above the spaces may by gravity enter the receptacle.

In the modification shown in Fig. 6, it showing a journal P, supposed to be fixed,the receptacle P is represented in the upper side of the journal, and the said receptacle is made to present a series of pockets by the interposition of the surfaces P3 P4, the acting faces of said surfaces occupying a position in the circle defined by the exterior portion of thejournal. Preferably this receptacle when made in the box will he at the lower side of the box and when made in the stationary journal will be made in the upper side of the journal, the receptacle thus being placed at points where the pressure of the load is least IOO IIO

upon either the box or the journal, whichever contains the receptacle, the receptacle being, however, always either in the box When stationary or in the journal when stationary.

In some instances hardened-steel balls within the flanges of the bearing-rollers crystallize by the hammering action referred to and disintegrate and entier the bearing; but the crystallization of the flanges is obviated by providing the space E2, hereinbefore referred to, between the exterior iianged end of the rollers and the inner surface of the box and the outer surface of the journal over which the bodies of said bearing-rollers travel.

The great object to be attained in the construction of roller-bearings is to maintain the most complete alinement possible of allparts of the bearing with the axial center of the journal, and if this alinement-can be made and maintained substantially perfectly the bearing would become practically indestructible. Hence it will be seen that the effectiveness and durability of the bearing depend upon the more or less perfect alinement of the parts, and in the production of my novel bearing I have aimed to secure such alineinent to the highest degree and maintain said aliuement.

By the term fixed as applied to the spindles or roller-alining means in this application I mean non-rotating.
